Concrete
canvas is a soft cloth soaked in cement that undergoes a hydration
reaction when exposed to water and hardens into a thin, waterproof,
and fire-resistant durable concrete layer. The cement blanket is
made of a three-dimensional fiber matrix woven from polyethylene
and polypropylene filaments, and contains a specially formulated
dry concrete mix. The main chemical components of calcium aluminate
cement are Al2O3, CaO, SiO2, and Fe2O3. The bottom of the canvas is
covered with a polyvinyl chloride (PVC) lining, ensuring that the
concrete canvas is completely waterproof. During on-site
construction, there is no need for any concrete mixing equipment.
Simply water the concrete canvas or immerse it in water to cause
hydration reaction. After solidification, fibers play a role in
strengthening concrete and preventing cracking. Currently, the
thickness of the cement blanket is *0mm
2、Advantages of concrete canvas products &
The main characteristics of concrete
canvas
1) Easy to use
concrete canvas
Concrete
canvas can be provided in bulk in large rolls. It can also be
provided in rolls, facilitating manual loading and unloading and
transportation, without the need for large lifting machinery.
Concrete is prepared according to scientific proportions, without
the need for on-site preparation and without excessive hydration
problems. Whether underwater or in seawater, cement blankets can
solidify and form.
2) Concrete
Canvas Rapid Solidification Forming of Concrete
Canvas
Once the
concrete canvas undergoes hydration reaction after watering, it can
still undergo necessary processing on the size and shape of the
cement blanket within 2 hours. Within *4 hours, it can harden to
*0% of its strength. It is also possible to achieve rapid or
delayed solidification using special formulas according to the
special requirements of users.
3) Concrete
canvas is environmentally friendly
Concrete
canvas is a low-quality low-carbon technology that uses up to *5%
less materials than commonly used concrete in many applications.
Its alkali content is limited and its erosion rate is very low, so
its impact on the local ecology is
minimal.
4) Flexibility
of concrete canvas application
Concrete
canvas has good drapability and can adhere to the complex shapes of
the covered object surface, even forming a hyperbolic shape. The
cement blanket before solidification can be cut or cut freely with
ordinary hand tools.
5) Concrete
canvas material with high strength
The fibers in
concrete canvas enhance material strength, prevent cracking, and
absorb impact energy to form a stable failure
mode.
6) Long term
durability of concrete canvas
Concrete
canvas has good chemical resistance, resistance to wind and rain
erosion, and will not undergo UV degradation under
sunlight.
